I claim:

1. Apparatus of the class described comprising a plunger, a tool removably connected to the plunger at one end, the tool having a plurality of faces and having cleaning or polishing elements mounted on the respective faces, the tool being angularly adjustable with respect to the plunger so that any selected element may be positioned upon the under side of the tool, a finger support spaced beneath the tool, and means for reciprocating the plunger.

2. Apparatus of the class described comprising a plunger having a recess in one end, a tool having a reduced end fitting in said recess removably to interconnect the tool and the plunger, said end and said recess being polygonal in cross section so that the parts may be angularly adjusted with respect to each other, the tool having several longitudinal faces, a cleaning or polishing element mounted on each face of the tool for selective arrangement on the under side of the tool, a finger support spaced beneath the tool, and means for reciprocating the plunger.

3. Apparatus of the class described comprising a plunger having a recess in one end, a tool having a reduced end fitting in said recess removably to interconnect the tool and the plunger, said end and said recess being polygonal in cross section so that the parts may be angularly adjusted with respect to each other, the tool having several longitudinal faces, a cleaning or polishing element removably mounted on each face of the tool for selective arrangement on the under side of the tool, a finger support spaced beneath the tool, and means engaging the opposite end of the plunger for reciprocating the plunger and tool.

4. Apparatus of the class described comprising a plunger, a cleaning and polishing tool removably connected to the plunger at one end, the tool being angularly adjustable with respect to the plunger, resilient means normally urging the plunger in one direction,

a cam bearing upon the opposite end of the plunger, and means for rotating the cam to move the plunger in the opposite direction against the action of said resilient means.

5. Apparatus of the class described comprising a reciprocating plunger, having a head at one end and a recess in its opposite end, a cleaning and polishing tool having one end removably mounted in said recess, a cam bearing against said head, a spring normally urging the head toward the cam, and means for rotating the cam to reciprocate the plunger.

6. Apparatus of the class described comprising a cylinder, a reciprocationg plunger, in the cylinder, a cleaning and polishing tool at one end of the plunger, a head at the opposite end of the plunger, a cam bearing against said head, a coiled spring surrounding the plunger and bearing against said head and against the end of the cylinder, and means for automatically rotating the cam to reciprocate the plunger.

7. Apparatus of the class described comprising a plunger, a tool removably connected to the plunger at one end thereof, the tool having a plurality of faces, cleaning or polishing elements detachably mounted upon the respective faces of the tool, the tool being angularly adjustable with respect to the plunger so that any selected element may be positioned upon the under side of the tool in operative relation to a finger held therebeneath, and means for reciprocating the plunger to move the cleaning or polishing element across the finger nail.

8. Apparatus of the class described comprising a plunger, a tool removably connected to the plunger at one end thereof, the tool having a plurality of faces, cleaning or polishing elements detachably mounted u on the respective faces of the tool, each ace having a longitudinal groove and each of said elements having a base portion slidable endwise into said groove, the tool being angularly adjustable with respect to the plunger so that any selected element may be positioned upon the under side of the tool in operative relation to a finger held therebeneath, and means for reciprocating the plunger to move the cleaning or polishing element across the finger nail.

In testimony whereof I afiix my signature.

CHARLES J. FOERSTER.
